SIGNALING DE'VICE. l

To @ZZ/whom t may cof/wcm:

Be it known that I, HAROLD W. Rinne, a citizen of the United States, residing at Cicero, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Signaling Devices, of which the following is a -full, clear7 concise, and exact description.

This invention relates to a signaling device but more particularly to a signaling device in combination with an electric switch.

The object of the invention lis the provision of a combined signaling device and electric switch of a compact construction.

In accordance with the invent-ion, a signaling device is provided with a movablecasing or housing' so arranged when moved to cause the actuation of contact springs.

A device of the character herein referred to is especially applicable'to telephone eX- change systems where the various lines terminating at a switchboard are multipled to several positions of the switchboard. A call therefor incoming on one of these lines first causes a signal to be displayed before one of the operators and if, at the time the call comes in, she is unable to oroperly handle the call, she may transfer the same to another operator located at a` position at which the particular line is multipled by the actuation of a key. In the construction of the switchboards which are adapted for this purpose7 the space allotted for the individual signal and keyis very small and it has been found very diiiicult to manufacture a satisfactory key for accomplishing this purpose,while with a signaling device and switch of the type asl herein described, the space occupied by both the lamp and switch is no greater than that occupied by the indi- Vidual signal.

A more definite understanding of the invention may be had yfrom the following description taken in conjunction with the accompanying drawing in which there is shown a signaling device embodying a feawhich is associated with `the trunk circuit C as regards to position No. l while that to the right of the dotted line 5--5 is located at position No. 2. Fig. 2 is a side View of 'the signaling device shown in Fig. l. Fig. lis'a sectional View taken 'along the broken line 3-3 of Fig. 2.

Referring now to the drawing and`especially to the signaling device as represent-ed by the numeral 57 the signaling device 5 has a hollow tube or casing' having an aperture "i' cut in one side thereof together with a` cap portion 8 which is adapted'to close one end of the casing 6. I y y The cap 8 is arranged so that it may be depressed andhas a portion 9 thereof which extends through the aperture 7. A transparent member 10 is mounted in the upper 'portion of thel cap 8 for enabling the oper- -ator`to detect the lighting ofthe lamp ll which is secured within the casing 6. r)The lamp 1l is securedin place by means of con- Jtact springs l2 and 13 which are adapted -to make contact with the terminals 14 and 15 of the lamp li.. These contact springs :together with contact springs 1S, 17 and 18 are secured to the casingl by'means of a Ibolt 19, are insulated from one another The by means of insulating members 20.

casing bis fitted with a pair of l. shaped pieces 2l and 22 for the purpose of mounting the same to a member such as 23. n

The Contact spring 17 is normally in engagement with contact spring 16 and is adapted to be disengaged therefrom and brought into engagement with contact springlSbymeans of the` portion 9 of the cap 8 which projects through the aperture 7 in the casing 6.

The switch or key part of the signaling device 5 as disclosed in the drawing is designed to be of the non-locking type but it it is desired to provide a key of the locking type, it will only be necessary to remove the member 24 which is secured to the cap 8, thereby lengthening the travel of the cap 8 and allowing the V shaped portion ot' the member 9 to engage a like portion of the contact spring 17. This contact will thereby be maintained until the operator -releases the same, *by pulling out on--the cap 8.

The operation of a device as heretQOre described as applied to a telephone exchange system is as follows: Let us assume that the operator at X desires to be connected with e telephone line terminating est Y- The operator at X would thereupon insert plug 25 into jack 26 associated with the trunk circuit@ `which terminates at Y. This having been done, she would then actuate .ringing key 27 for connecting a source of ringing current with ythe trunk circuit, the connection Iof which with the trunk circuit thereby causes fthe operation yof relay 28, the energizing circuit of which may vbe tra-,eed ,frein the .eem-ee 0f ringing airvent et .X three-gh ...the Y'loner :alternate Contact el ringinakey 2.7,:ri11g-.eenteeteeftheplui 25 .and/:the jack 2.6, @C endneter ...2.9, :rglrtfhend .normal eentecte 'relay 3.0, Winding ,of relay 2.8, cendzuletcri131, l.tip ecrit-.acts efthe `jack 2 6 and theplug 25 and the'upper alternate contactfof ringing key 27 to ground. Relay 28. `in operating, closes, at its contact an .energizing circuit for relay .32 which extends from battery through the winding of relay 32 andthe contact of relay 28 to .ground. The operation of relay 82 .thereby establishes a circuit including lthe lamp y11 of theisignaling device 5 located at position No. j1. This `circuit extends from battery through the right-hand contact'oi:1 relay 32, Contact springs 17, 16 and 18, the iilament of the lamp 11, contact yspring 12 and-the winding rofrelay Sto ground.- The establishment of Vthis cirou'it causes `the lighting ofthe lamp 11or :signaling the operaterat posit-ion yl'. 'Ehe attraction of theleft-hand `contact ol' relayr32 establishes a locking circuit -forrelay 32 extending from battery through the winding of relay 32, le-ttfhand contact of; relay 32, left-hand contact of relay30ito ground. This locking circuit will cause the `lam-p `1:1 -to remain lighted until the actuation of relay 30, as will be described hereinafter. Relay 33 is operated at this time `for connecting an auxiliary signal (not shown) in circuit with -a contact thereof. Relay 82, in operating, alsocauses the operation of the busy signals 8.4 and which are 4located at both positions No. .1

vand No. 2,the eperati-ngicircnitro whichex- Vas occasion demands.

tends from battery through the middle alternate contact of relay 32 and the winding of the magnets associated with the busy signals 34 and 35 to ground.

The operator at position No. l. upon observing the lighted condition of lamp 11, may thereupon insert the answering plug associated with her cord circuit (not shown) into jack 36 after whichshemay ascertain the number of the party with which the operator at X desires to be connected.

If the operator at position N o. Y,1 is un able to handle ,the eallshemaytrarsfer the same to another position such position No. 2. r1n doing this, she would vmerely depress the cap 8 of the signaling device 5 which thereupon .opens at Contact 17, the circuit including the ilament of the lamp 11 and establishes -a circuit including the lamp 37 located .et position No. r2. `This circuit extends Vfrom battery through the right-hand contlft of relay 32, Contact spring 17 and 18,1amp 87 and the winding of relay 38 lto ground. The operator vat position No. 2, upon observing the `lighted condition of lamp 37, inserts plug 39 yinto jack 40 which thereupon causes the venelfgizetienef relay 30 over a circuit-extendles .from battery through the winding 0f relay 41, sleeve contacts of the plug 39';an d the jack .40 ,and the williclng ef relay 3.0 :te groendlllfhen .rela-y 23.0 .is energized, l.the energizing circuit fier lrelief. 2.8 is 'breken at the light-hand .termal .Contact -Q-f A:relay .30. At thezeeme :time the lacking/circuit :forrelay 32 -is broken at the left-hand Contact of relay 30 and asa result the lamp is'extin ,guished The operator is now in a position to ascertain the number ofthe desired party and complete the connection with the line associated therewith.

The signaling device 3.7 located at position No. v2 may be of the type as described in connection with .position No. 1, or it may be an individual signaling device-or a lamp,

In many cases, Ahowever, it may be desirous to provideasignaling device of the same type as thatrepresented bythe .numeral 5 -for the purpose of transferring the call tostill another position where the operator is Vnot so busy and is able to properly .handle 4the call.

It is, however, obvious that a device of the character as herein described `is ap.- plicableto .systems other than telephone .sys-

tems and although it lis described in ,conw

nection with a telephone system, it is not intended to limit the invention -to that particular use.

What is claimed is:

1. A signaling 4device comprising a casing, a lamp enclosed by said casing, a contact spring mounted onthe exterior ofsaid casing, said casing having two relatively movable parte, .one of said-parts having Lampert means adapted to slide through an aperture in the other of said parts to engage said Contact spring, and circuit connections controlled by said Contact spring for causing the operation of said lamp.

2. A signaling device comprising a casing, said easing having a stationary part and a movable part, said stationary part having an aperture in one side thereof, ac-

tuating means attached to said movable part and extending through the aperture in said stationary part, and Contact springs mounted on the outside of said stationary part and arranged to he engaged by said actuating means.

In Witness whereof, I hereunto subscribe my name this 3rd day of Nov. A. D., 1919.
